Hey Jerry,

Agreed, the correct destination for the LookupName call in winbindd
needs more investigation.  This is particularly important when trusted
domains are involved.

I'm curious as to why a direct query to the DC with which the name is
qualified isn't the best option.  It seems, that if a domain is within
the same forest or trusted, that we should be able to query it directly.
